Abstract
A casting ladle for improving the technique in the pour process of metallurgical molding. The casting ladle includes a bowl portion that has a bottom wall and a peripheral wall. The peripheral wall extends upwardly from a perimeter edge of the bottom wall such that the peripheral wall and the bottom wall define an interior space. The present invention has an open top such that the interior space is adapted for receiving molten metal. A spout outwardly extends from the peripheral wall such that the spout is adapted for controlling pouring of the molten metal.
Claims
exact text as granted — not AI-modifiedI claim:
1. A casting ladle for pouring molten metal comprising:
a bowl portion having a bottom wall and a peripheral wall, said peripheral wall extending upwardly from a perimeter edge of said bottom wall such that said peripheral wall and said bottom wall define an interior space having an open top such that said interior space is adapted for receiving molten metal;
a spout outwardly extending from said peripheral wall such that said spout is adapted for controlling pouring of the molten metal; and
said spout having a channel and a pair of side portions, each of said side portions are positioned between said channel and said peripheral wall, said side portions being substantially coplanar such that said side portions are adapted for permitting the molten metal to be poured from said bowl portion, a top surface of said side portions being aligned with an interior surface of said bottom wall of said bowl portion such that said side portion are adapted for permitting molten metal to be poured directly from said bottom wall of said bowl portion, said channel outwardly extending from said top surface of said side portions such that said channel is positioned below said interior surface of said bottom wall, said channel of said spout being adapted for facilitating precise pouring of the molten metal from the bowl portion.
2. The casting ladle as set forth in claim 1 , wherein said channel of said spout has a substantially arcuate cross-section taken transverse to a longitudinal axis of said channel such that arcuate cross-section of said channel is adapted for reducing the amount of air trapped in the molten metal when the molten metal is poured from the bowl portion.
3. The casting ladle as set forth in claim 1 , further comprising:
a handle outwardly extending from said peripheral wall such that said handle is adapted for facilitating pouring of the molten metal from said bowl portion.
4. A casting ladle for pouring molten metal comprising:
a bowl portion having a bottom wall and a peripheral wall, said peripheral wall extending upwardly from a perimeter edge of said bottom wall such that said peripheral wall and said bottom wall define an interior space having an open top such that said interior space is adapted for receiving molten metal; and
a spout outwardly extending from said peripheral wall such that said spout is adapted for controlling pouring of the molten metal;
wherein said spout has a channel and a pair of side portions, each of said side portions are positioned between said channel and said peripheral wall, said side portions being substantially coplanar such that said side portions are adapted for permitting the molten metal to be poured from said bowl portion, a top surface of said side portions being aligned with an interior surface of said bottom wall of said bowl portion such that said side portion are adapted for permitting molten metal to be poured directly from said bottom wall of said bowl portion, said channel outwardly extending from said top surface of said side portions such that said channel is positioned below said interior surface of said bottom wall, said channel of said spout being adapted for facilitating precise pouring of the molten metal from the bowl portion;
wherein said channel of said spout has a substantially arcuate cross-section taken transverse to a longitudinal axis of said channel such that arcuate cross-section of said channel is adapted for reducing the amount of air trapped in the molten metal when the molten metal is poured from the bowl portion;
wherein a handle outwardly extending from said peripheral wall such that said handle is adapted for facilitating pouring of the molten metal from said bowl portion.Join the waitlist — get patent alerts
